QUERTANIN® CHOC is a preparation of stave oak heartwood quality ellagic tannins and gallic tannins, using LAFFORT’s Instant Dissolving Process (IDP). For post-vinification use in red, rosé and white wines.
Used during fining, QUERTANIN® CHOC’ is a preparation of ellagic and gallic tannins that:
• Enhances wine structure and palate length.
• Regulates oxidation-reduction phenomena during maturation in barrels or during micro-oxygenation.
• Creates an environment rich in ellagic tannins in used barrels, similar to that of new barrels.
• Improves clarification.
After the addition, it is recommended to carry out normal rackings until fining or bottling preparation.
